In the utility model, under described pump seat, be connected with oil draining system and drainage.Described pump cover is connected with venting rinse-system.Described oil draining system, drainage are all connected with same outer pipe with venting rinse-system.Centered by the two-stage horizontal type horizontal split pump of the secondary single suction of described first-stage double-absorption, line supports.
The beneficial effects of the utility model are: the utility model can be provided with different sealing configurations according to different operating mode, favorable sealing property, and adopt double flow channel structure, compact structure, beautiful shape, hydraulic efficiency and anti-cavitation performance are higher simultaneously; Pump seat is established a suction port and a discharge opening, make not need during maintain and replace mechanical seal to dismantle pipeline, pump seat, motor and pump cover, fast easy to maintenance.And first stage impeller is double-entry impeller, secondary impeller has equalizing orifice with balancing axial thrust.
Accompanying drawing explanation
Fig. 1 is the structural drawing of an embodiment of the present utility model.
Embodiment
To illustrate below in conjunction with accompanying drawing and embodiment further illustrates the utility model.
As shown in Figure 1, the two-stage horizontal type horizontal split pump of the secondary single suction of first-stage double-absorption of the present utility model, comprise pump cover 12, pump seat 1 and rotor part fill 14, described pump cover 12 covers on described pump seat 1, to run through described rotor part in described pump seat 1 and fill 14, the two ends that described rotor part fills 14 pass described pump seat 1, described rotor part fills on 14 and is provided with two impellers 11, described two impellers 11 are arranged in described pump seat 1, described pump seat 1 is provided with a suction port and a discharge opening, the two ends that described rotor part fills 14 be separately installed with front axle bearing portion fill 15 and rear axle bearing portion fill 8, described front axle bearing portion fills between 15 and described pump seat 1, described rear axle bearing portion fills between 8 and described pump seat 1 and is equipped with oil blocking cover 13, described impeller 11 and described pump seat 1, impeller increasing back sealing ring 10 is equipped with between pump cover 12, seal ring 3 before impeller, low voltage terminal Seal cage seal ring 2, high voltage terminal seal ring 4 and intermediate seal ring 5.
In the utility model, be connected with oil draining system 7 and drainage 6 under described pump seat, described pump cover 12 is connected with venting rinse-system 9, and described oil draining system 7, drainage 6 are all connected with same outer pipe with venting rinse-system 9.Centered by described two-stage horizontal type horizontal split pump, line supports.
Structure of the present utility model is from compact type pumps such as traditional integral pump pin, water-cooling type bearing support, the huge type of single spiral case equal-volume split type technique pump pin till now, alternative type of cooling (water-cooled, air-cooled, naturally cool), double flow channels, not only make the profile of pump more attractive in appearance, and further increase the reliability of pump.
In the utility model, the suction port of the two-stage horizontal type horizontal split pump of the secondary single suction of first-stage double-absorption and discharge opening all on fixed pump seat, when pump is keeped in repair, without the need to detaching pipelines and motor, and maintain and replace mechanical seal and bearing time, do not need to tear pump seat and pump cover open, dismounting is extremely simple.The runner of pump adopts double flow channel, but not the guide-vane of general multistage pump, and therefore pump can keep higher hydraulic efficiency, and the efficient district of pump is wide, and the efficiency of pump is all up to state standards more than A line or A line.
In the utility model, first stage impeller adopts single-stage double-suction form, improves the anti-cavitation performance of pump.Secondary impeller has equalizing orifice with balancing axial thrust, and spiral case adopts double flow channel structure, and radial force is balanced, and the bearing at pump seat two ends only need bear very little axial force and radial force, substantially prolongs the working life of bearing like this.
In the utility model, pump housing oil draining system, drainage, the outlet of venting rinse-system all gather and to be connected with the external world, meet environmental requirement, the utility model makes two stage pump from without Monitoring and Controlling remote monitoring up till now, really achieve on-the-spot unattended, integrate with completely with external advanced pump level.
